Highlights
The local Windows array-to-array
migration was a success.
2. Migration groups were configured on source and target by the implementation
team. The team, with offsite Softek support, created mount points to resolve
issues related to insufficient drive letters caused by the number of volumes
to be migrated.
3. TDMF full refresh was initiated in loop back configuration. Full refresh
took approximately 24 hours and was performed online without any appli-
cation impact.
4. With TDMF operation in normal mode, the team validated the data migrated
to the new storage array by using TDMF software's checkpoint function.
5. During Tuesday downtime, the application was stopped and source volumes
were removed. The target volumes were renamed, and the application was
placed back into production using new arrays.
6. Old arrays were decommissioned.
